There were too many deer in the forest. So they unleashed the wolves without any idea what would happen.
When the deer killed off the forest, they decided to let the wolves loose to fix it. We had no idea what exactly we had done.
One of the most exciting scientific findings of the last 50 years is called a trophic cascade.
A trophic cascade starts at the top of the food chain and tumbles to the bottom. One of the best examples of this happened in Yellowstone National Park in 1995 when wolves were reintroduced.
Wolves are really good at eating deer. But as it turns out, because of their deer diet, they also help lots of other animals survive.
Basically, wolves see deer/elk like this:
Humans killed all the wolves in Yellowstone National Park 70 years ago. And the deer population exploded.
Humans, being the controlling type in our relationship with Earth, tried to control the deer population. But deer are super-good at showing each other lots of love ... so the population grew and grew. In 1995, we reintroduced wolves to the park, and they immediately started killing the deer. But that's the least remarkable part. The wolves actually started changing the behavior of the deer.
Deer started avoiding certain parts of the park — mostly the places where they could easily be trapped.
And those areas started to regenerate! The trees grew five times the height they had been!
Barren parts of the land became lush forest filled with new animals. Songbirds moved back in because of all the new trees!
Beavers loved the new trees, so they started moving in too! They built some dams, and that created ponds in the rivers. Ducks, muskrats, otters, and fish moved in.
The wolves started killing coyotes, and that allowed for mice and rabbits. Which brought foxes, weasels, and owls back to the park.
Bald eagles and hawks decided they wanted in on the action too.
Then grizzly bears moved back as well!
You see, the new trees were suddenly growing berries they could eat and thrive on.
The wolves even changed the behavior of the rivers. With less erosion, more pools formed, and the rivers stopped meandering. They became more fixed in their course.
Wolves changed not just the ecosystem, but its actual topography.
We are all connected. And what we do to other species affects you and me.
Now, go hug a tree and thank a wolf today.
There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
